(92) Achatinella {Achatinellastrum) ligata Smith. 



Achatinella ligata Smith, P. Zool. Soc. London, 1873, p. 76, pi. ix. fig. 13. 

 Achatinella bellula Smith, t. c. p. 77, pi. ix. fig. 8. 



I fancy these two forms are only varieties of one species ; they approach A. 

 nympha Gulick. 



Hab. Oahu, Waimolu (Smith) ; Panoa and Nuuanu (Baldwin) ; ridges round 

 Nuuanu, Waimea, and beyond head of Panoa Valley (Perkins). 



(93) Achatinella {^Achatinellastrum) livida Swainson. 



Achatinella livida Swainson, Zool. 111. pi. cviii. fig. 2. 



Achatinella emmersonii Newcomb, P. Zool. Soc. London, 1853 [1854], p. 156, pi. 



XXIV. fig. 74. 

 Achatinella viridans Reeve, Conch. Icon. Achatinella, sp. 25 [nee Mighels]. 

 Achatinella reevei C. B. Adams, Contrib. to Conch. 1850, p. 128. 

 Achatinella consanguinea Smith, P. Zool. Soc. London, 1873, p. ']i, pi. ix. fig. 3. 

 Nee A. livida Pfeiffer, P. Zool. Soc. London, 1845, p. 89 [ = ^. vnlpina Per.]. 

 According to Dr Hartman, Mr Smith's species is probably a variety of A. 

 colorata; from the specimens I have seen, I think it rather belongs here. 

 Hab. Oahu, Waialua (Newcomb, Baldwin); Ahuimanu (Smith). 



(94) Achatinella {Ac hat inc I last rum) longispira Smith. 



Achatinella longispira Smith, P. Zool. Soc. London, 1873, p. Ti^ pi. ix. fig. 5. 



Placed by Dr Hartman as a synonym of A. viUpina, but the present species is 

 much more slender in form; I should be inclined rather to refer it to the group of 

 A. olivacea. 



Hab. Oahu, Halawa, Ahuimanu (?) (Smith). 



(95) Achatinella {Achatinellastrum) multizonata Baldwin. 



Achatinella {Achatinellastrum) multizonata Baldwin, P. Ac. Philad. 1S95, p. 215, 

 pi. X. figs. I, 2 [animal described]. 



The shells collected by Mr Perkins from ' round Nuuanu' are in no sense typical 

 of this species, they appear to be forms shewing links between it and A. bellula Smith 

 { = ligata Smith) ; indeed the two may prove to be forms of one variable species. 



Hab. Oahu, Nuuanu Valley (Baldwin); ridges round Nuuanu and Waimea 

 (Perkins).
